patch to get --with-png working on FreeBSD

[ScottJ]

I was having trouble getting configure to enable PNG on FreeBSD 8.1-rel. Googling for "test: no: unexpected operator" I discovered viewtopic.php?t=16644&p=61122, and I found the same problem exists for PNG. I patched up configure and everything seems to work.

Code: Select all

*** configure   Sun Oct  9 11:48:22 2011
--- configure.fixed     Tue Oct 11 22:21:26 2011

    if test $passed -gt 0; then
      for var in 5 4 2 '' ; do
!       if test "$have_png" == 'no' ; then
!         if test "x${var}" == 'x' ; then
            pnglib='png'
          else
            pnglib="png1${var}"
